Settle in for a 2.5-hour drive to Agrigento, once one of the wealthier and more famous cities in the Greek colonies, for exploration on foot of the Valley of Temples, a UNESCO World Heritage Site. A two-hour guided walk is a thrilling opportunity to discover one of the most significant archaeological sites in the world. There are eight different temples built between 510 B.C. and 430 B.C. and various other artifacts and remains. Your tour takes in the Temple of Jupiter (Zeus) built to commemorate the city's victory over Carthage. See Tempio dei Dioscuri, a hex-style temple with only four of its columns remaining. Probably the oldest of the Agrigento temples, and built in the ancient Doric style, is the Temple of Hercules, and the Temple of Concord is the largest, most majestic and best-preserved of the Doric temples in Sicily. Continue on to a local restaurant for lunch before settling back into the motorcoach for the drive to port.
